Hi reporting in from Canada where the proprietary names for these prescription drugs are different so for clarity sake I will call them by what they are what you call Chantix is varenicline tartrate, what you call Welbutrin is Bupropion Hydrochloride. In Canada it is recommended to try NRT (nicotine replacement therapy) before trying the meds. Varenicline and Bupropion operate in different ways, both were initially developed as anti-depressants, and both of them can have serious side effects. And with both of them you still have to use self control. I am currently using Varenicline which was prescribed by my dentist (dentists can prescribe anti smoking meds in Canada because of oral health concerns) and with the packet comes instructions. Also that if you have any problems to contact pharmacist. Which I did. And I spoke with pharmacist and now instead of taking 2 whole tablets each day, I take 1/2 tablet. I had bad nightmares, heartburn, dry throat and mouth, constipation. insommnia. you name it. But some of these effects were nicotine withdrawal effects too. It is hard to untangle withdrawal from side effects of meds. Now I drink tons of water and like I said only on 1/4 of the recommended dosage. Tomorrow is my one week smoke free date! I also like the low dosage becasue, if you are on these meds the nicotine receptors in your brain don't die. And a lower med means that more of them die and this is what I want to happen. You really should talk to your Dr. or Dentist and a Pharmacist too. to talk to a Pharmacist you don't need to make an appointment. check this out..... there is lots of info online for both of these chemicals. What is the Difference Between Zyban and Champix? Zyban is Welbutrin. (in Canada and UK)
